HAND RULE PUNCH FOR PRINTERS Filed Sept. 25, 1952 Albert E. Neudauerlum'nlor United States Patent This invention relates to new and usefulimprovements in punching devices and the primary object of the presentinvention is to provide a device for punching slug'acco'm' modatingslots in printingrules.

Another important object of the present invention is toprovide a punchthat is secured to a graduate'd'base strip so that a printing "rulemaybe held upon'the base strip and"pr0vide d"witha slot as the punch isactuated."

A further object of the present invention is to provide a handrulepunch'forprinting rules involving a stop 1' member that islongitudinally adjustably secured'for a printing rule, whereby "slots'may be 'cut 'in the rule at preselected space intervals.

A still furthe'raim of the present'inv'ention is-to provide a hand rulepunch for printers which is extremely: simple" and practical'inconstruction, strong and-reliablein use,

small and compact in structure, efiicient and durable in operation,inexpensive to manufacture, and otherwise well adapted for the purposesfor which the same is intended.

Otherobjects and advantages-residein' the detailsof constructionand-operationas more-fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming 'part' hereof,wherein-"like numerals refer tolike parts'throughoutfand in which:

Figure 1 is a perspective view of'the'pre'sent invention;

Figure '2 is a perspective-view showing printingrul'es processed by thepresent invention, operatively engaged with printing slugs;

Figure 3 is an enlarged fragmentary transverse vertical sectional viewtaken substantially on the section line 33 of Figure 1 and showing aprinting rule in position to the base strip and punch;

Figure 4 is a perspective view of a finished printing rule after thesame has been provided with slots;

Figure 5 is a group sectional view of the upper and lower punch elementsused in the invention;

Figure 6 is a plan view of the upper punch element taken substantiallyon the section line 6--6 of Figure 5;

Figure 7 is a fragmentary perspective view of one type of slug used inconjunction with the printing rules slotted by the present invention;

Figure 8 is a modification of the printing slug; and

Figure 9 is a further modification of the printing slug.

Referring now to the drawings in detail, wherein for the purpose ofillustration, there is disclosed a preferred embodiment of the presentinvention, the numeral 10 represents an elongated rigid base striphaving its rear longitudinal edge turned upwardly to form a guide ledgeor flange 12. The upper face of the strip 10 is provided withlongitudinally spaced, transverse graduations forming a scale 14.

The end portions of the strip 10 are provided with apertures 16 and willreceive fasteners 18 which are engaged in the upper ends of cylindricalsupporting feet or pins 20. The fiat lower ends of the pins 20 areintended to rest upon a horizontal surface to support the strip 10 in ahorizontal position.

The fiatjaw end 22 of a lower lever or handle 24 is suitably securedtothe'unde'rsurface of str'ip 10, at substantially the"ceiite"r of 'thestrip"10. Lever 24 extends at right angles 't'o'the strip 10 and'is-channel shaped in a V vcross section to includespacedparallelvertical flanges 26 between which there is-received a jawportion 28.

A horizontal pin 29 extends through flanges 26- and portion 28 topermitswinging or locking movement of 'jaw portion 28 relativetothe' jawend 22.

An upper channel shaped lever or handle30 overlies and faces the lever24 and includes a forward bifurcated end 32 that is pivoted,as at34, "tothe rear end of jaw portion 28. A pit'rnan' or link 36 forming a fulcrumis terminally pivotally attached between the' flanges of the 1 ,levers24v and 30: A coil spring'38 'is biased between the levers 24 and 30to'urge the lever 30"raised relative to the lever 24 and hence-the jawportion 28 spacedfrom the strip' 10 and jaw' end 22".

The forwardlyextending fiat'forward end 40'0f jaw- ,portion 28isprovidedwith a recess '42 that accom-- modates the reduced upper endportion 44 'of a male 'die' or punch element 46having'a T-shaped cuttinglug 48" on'its lowerface." A "scr'e'w50 extends downwardly through anaperture in th'ee'n'd 40and is threaded into a .recess 52 in thepunch'element'46 to secure the central part of punch element"46' againstthe fiat undersurface of the end 40.

T-sha'ped lug 48 is progressivelyreduc'e'din thickness from front torear, as shown in Figured, so that as the .end"40 is'moveddownwardly,'the lower face of lug48 will be"substantiallyparallelto the base strip 10.

opening 561* The pu'n'ch' element 60is provided with" a lug 48 as thepunch 'eleme'nt 46"is moved: downwardly relative to basestrip"10."

A pair of downwardly" facing"channel's"64' overlie the upperface' of"the basestrip lfland'parallel the" flange 12. The channels 64 areprovided with attaching flanges 66 that are apertured to receive theupper ends of threaded studs or lugs 68. Studs 68 are suitably fixed ontheir lower ends to the strip 10 and extend upwardly from strip 10 toreceivably engage wing nuts 70.

A stop member 72 is slidably adjustably mounted on the base strip 10 andcoacts with flange 12 in retaining a printing rule R in position to thepunch. Stop member 72 includes a rod 74 having a transverse stop 76 atone of its ends that extends perpendicular to the flange 12. The rod 74is slidably received in the channels 64 and is clamped against the upperface of the strip 10 by the channels as the nuts 70 are tightened, inorder to adjust the rod 74 longitudinally of the strip 10 for locatingthe stop 76 relative to a predetermined graduation of scale 14.

In practical use of the present invention, a printing rule R is placedover the strip 10 with one of its longitudinal edges resting againstflange 12 and with one of its end edges engaging the stop 76. Thebeveled longitudinal edge E of rule R overlies the punch element 60 andunderlies the male punch element 46. As the handle 30 is forceddownwardly toward the handle 24, jaw portion 28 will be rocked to forcethe T-shaped lug 43 through the rule R and into the punch element 60.The rule R is moved longitudinally relative to the strip 10, after thestop member 72 has been adjusted, so that a plurality of longitudinallyspaced T-shaped slots S may be formed in the beveled edge E of the ruleR.

After a predetermined number of the rules R have been slotted, theflanges of T-shaped printing slugs are extended through registeringslots in a group of the Patented Feb; 14,- e-

rules, as shown in Figure 2. The slugs may be of various types as shownin Figures 7, 8 and 9 with the printing facings or edges thereofcoplanar with the beveled edges E of the rules R. The printing face F1of the slug Si shown in Figure 7 is V-shaped to permit printing of twoparallel relatively thin lines; the printing face P2 of the slug S2 inFigure 8 is flat to print a wide line; and the printing face P3 of theslug S3, shown in Figure 9, is beveled to print a thin single line.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.
